Definitions

  • the body or carcase of the tire is called upon to transmit such stresses from the tread of the tire through various superposed layers until they are transmitted to the hub or rim.
  • the object of the present invention is to provide an improved adhesion between the elements constituting the body of the tire of a nature such as to provide a greatly increased resistance to iorces tending to separate them whereby the efflciency and capacity in service 01' the tires shall be greatly enhanced.
  • the present invention aims at preventing the development of tread, undertread or casing ply looseness particularly between rubber-cotton joints in the tire such as may be due to some one, or to a combination, of the causes 5 set forth above.
  • discontinuous fibres are provided in the layers of rubber in contact with the textile material of the tire.
  • the fibres may be carded or combed fibres and 10 may be initially coated with rubber prior to their introduction into the rubber compound which ultimately forms the rubber layer in contact withthe textile material.
  • One or more layers of rubber containing fibres 15 may be interposed between the under tread and breaker strip or strips. Alternatively or in addition one or more layers of rubber having imbedded fibres may also be interposedbetween the breaker strip or strips and the cord or fabric, plies constituting the body of the casing.
  • One or more layers comprising rubber having fibres incorporated may also be interposed between any or all of the plies or pockets of which heads, toes, or other fabric and rubber insulating layers adjacent thereto.
  • the fibres may be of vegetable origin or of mineral origin, of animal origin and of synthetic origin.
  • the fibres incorporated may consist wholly or partly of vegetable fibres such as cotton, hemp, jute, ramie, sisal, or of mineral, fibres such as asbestos, slag-wool or glass wool, or of animal fibres such as hair, wool, or silk, or 35 of artificial fibres such as artificial silk, hair, or synthetic cellulose products or of mixtures of such fibres.
  • the fabric components of the tire may consist 01 or comprise weftless. or woven cord or canvas. 40
  • the manufacture of the kind of tires described may also be characterized by a process comprising dispersing discontinuous fibres within a rubber compound with which the cord or textile layers are topped. and if desired by an initial 45 process wherein the fibres are coated prior to dispersion with a composition containing rubber, and in one composition the mix may include 5 to 10% of fibres by weight, but other proportions are not excluded. It has been found that 50 improved results are obtained up to an amount of fibre 01' 20% by weight of the rubber content oi the mixing.
  • fibres be introduced in a dispersed manner in order to prevent any 55 tendency to matting, and the formation of agglomerates.
  • the fibres are employed in carded or combed form and their introduction into the tire may be effected directly in this form.
  • the introduction is facilitated and effected by first coating the fibres with a thin rubber layer or envelope in any convenient mannet.
  • the fibres employed may be of any suitable length or thickness as may be found desirable the fibres of heat insulating or heat conductive character may be incorporated and any of the kinds of fibres mentioned may be used with or without admixture with one another in the proportion required to provide the required additional resistance to separative stresses.
  • insulation layers of rubber are employed, it will be understood that any one or more or all of such insulation layers may themselves comprise dispersed fibres or may be laid upon an adjacent surface whether of cord or rubber which has been topped with rubber containing dispersed combed or carded fibre of the kinds and in the manner specified.
  • Fig. 1 shows a cross-section of a tire embodying the invention
  • Fig. 2 is a section cut along the plane of the topping rubber and showing a section of a cord through its center, this drawing corresponding to a photomicrograph of a magnification of about 50
  • Fig. 3 is a similar section on a plane passing through the edge of the cord
  • Fig. 4 is a radial section of a .portion of the tire parallel to the axis of the tire and substantially at right angles to the sections 2
  • ii Fig. 5 is a section on a somewhat larger scale, as for example, in magnification of about 65 at right angles to the plane of the topping rubber and showing a section of a cord surrounded by fibre and lighter bands of cushion and insulation rubber.
  • Fig. 1 the tire is shown tread portion l0, bead portions as comprising a II and connecting side walls ii.
  • a number of usual cord fabric extend from one of the bead edges and tread to the oppolayers l3 through the. side walls having superposed layers of site bead edge.
  • Breaker strips Il may be provided in the tread portion between the cord fabrics and the tread. This construction is a usual tire construction.
  • Each of the fabric layers [3 and breaker strips I 4 is made up of a number of cords l5 shown in Figs.'2, 3, 4: and 5. These cords are embedded in a mass of rubber l6 which contains fibres l'i dispersed throughout the rubber in separated unmatted condition or position.
  • the fibres I! extend from a close association with the cords l5 out and through the mass of rubber ii.
  • the masses of rubber l6 enclosing one cord fabric may be united directly with or be integral with the mass of rubber containing an adjacent cord fabric or it may be separated from the adjacent cord fabric and embedding rubber by means of a separating or insulating layer l8 as shown in Figs. 2 and 6.
  • the discontinuous separated fibres ll serve to firmly unite and anchor the textile components into the rubber, so that the plys cannot be stripped from the intermediate rubber layers as in those cases where there is no anchorage between the plys and the rubber layers.
  • a pneumatic tire comprising a rubber body having superposed layers of fabric embedded therein throughout the tread and side wall areas of said tire, and separated from each other by intervening rubber composition, said composition having fibers individually dispersed therein and in contact with the fabric in said tread and side wall areas.
  • a pneumatic tire comprising a rubber body fabric embedded therein in "the tread and side wall areas, and separated from each other by intervening rubber composition, said rubber composition containing fibers individually dispersed therein and in contact with said fabric throughout the tread portion thereof, the quantity of fiber in said intervening rubber composition being less than the quantity of rubber therein.
